John's mum still treats him like a teenager, asking him where he's going and what time he'll be back

Dr Marco Tosi, who led the research at the London School of Economics and Political Science, said: “When children leave home, their parents find a new equilibrium. But when an adult child moves back, it is a violation of that.”

Her parents think she's made the right decision to move back home June says: “When the kids finally left, we had high hopes of ­rekindling our romance . But when you have another adult living with you, you can’t have romantic nights and do what you like, when you like.

“When April moved back the first time, she did treat it like a hotel.

“But the April who came back this time is different. She’s more focused and going to uni. With the cost of things, it made more sense for her to move home.”

Theresa, 27, and mum Tracey, 52

SUPPORT worker Theresa Johnson, 27, has boomeranged back to mum Tracey’s home in Doncaster EIGHT times – most recently with her four-year-old son Cody.

Tracey says she misses having peace at home and feels as if she needs to help out since her space is now theirs too

Mum-of-two and catering assistant Tracey, 52, says: “My house has had a revolving door for my kids. I had planned on redecorating a bedroom into a hobby space but that hasn’t happened. It’s lovely to have my grandson here but when their home is your home, you naturally feel you have to help out and sometimes take over.

“After working all day I can no longer guarantee there will be peace at home and I can’t plan to go out because I need to check with Theresa first to see if she needs help with Cody.”

Will, 26, and mum Helena, 57

WILL MASHETER, 26, moved back in with mum Helena, 57, in Morden, South West London, 18 months ago to save up to buy his own place.

Helena doesn't think she'll be able to have a man around the house whilst her son is still living at home

Will, a promoter, says: “I was ­sharing an apartment and it was always untidy. I hated paying off a mortgage for someone else, so I moved back home. Now I can save.”

Single Helena, a funeral home worker, says: “When you live on your own, you get used to your own space. It would be difficult if I met someone, as it would be awkward to have a man in the house with my son there.

“I also like to walk around the house naked, which is more ­difficult now.
